To all whom it may concern I Be it known that I, IIENRY R; KINDT, asubject of the'Empei-or of Germany, residing at Floral Park, in thecounty of Nassau and State of New Yorkyhave invented cer tain new anduseful Improvements in Stipple-Brushes; and I do herebyzde'clare thefollowing to be anfull, clear, and exact de-" scription ofthe invention,such as will enable others skilled in theart to which it appertainstomake and use the same.

My invention consists in the novel-features hereinafter describedreference being had to the accompanying drawing, which illustrates oneembodiment of the invention selected by me for purposesof illustration,and thesaid inventionis fully disclosed in the following descriptionandclaims.

Referring to the drawing, Figure l rep resents a side elevationof'astippl'e brush embodying my invention. .Fig-Q is a'bottom plan viewofthe brush with the handle broken away. Fig. 3 is a detail perspectiveview drawn to an enlarged scale of one of the stipple units which ,Iemploy in'iny im proved brush. Fig. at is a detail view showing aportion of the brush head with'one of the stipple units secured theretoand illustrating the manner in which thestippleunit may be adjusted.

The object of my invention 'is'to provide a stipple brush to be usedmore especially in connection with oil paints, for the purpose ofproducing stipplcdsurfaces and particularly imitation marble effects.

My invention also comprises a new stipple unit of peculiar form andconstruction, hereinafter described, as well as the brush itself, whichincludes abrush head provided with a plurality of these stipple unitsarranged in a predetermined relation.

In Fig. 3 of the drawing I have shown one of the stipple units which Iprefer to em ploy in the formation of -my improved brush. This unitcomprises a bifurcated body having two approximately parallel leaves orlips united at one end vby a body portion which forms the support forthe unit and which is preferably provided exteriorly with a channelportion, for eX- ample, as shown in Fig. 3, the stipple unit comprisingthe leaves or lips 1-1, having substantially straight and parallelstipple edges 22, the said leaves or lips being united by the bodyportion 3 which is provided at its bottom or exterior with sepa- 1screws.

rated head engaging portions: 55 prefer ably separated by a channel at.I The stipple unit is formed of flexiblematerial such as rubber orleather, but preferably rubber as it is non-absorbent and is easily keptclean.

The body portion 3 is preferably provided with one or more apertures 6-6to receive a screw 7 or other retaining means by which the stipple unitmay be secured to the head orbody of the'brush, as indicated-in Fig,

and as shown in that figure, the lips or leaves 1-1 may be adjustedtoward and from each other by tightening or loosening the retainingdevice as the screw 7'. It will be seen that the supporting edges 5-5 ofthe main body are substantially in line with theleaves l1 andthat thechannel 4i between them' permits the central portion of the'body 3 to bemore orless depressed, thus regulatingthe distance between the leaves'or lips l-l. r i I In forminga brush embodying this improved stippleunit, I provide a brush head indicated at 8 inFigs. 1 and 2, which maybe of any desired size and shape according to "the work'to be done, itbeingshown in this instance in the form of a square and being preferablymade of wood although it may be made of; other Ematerials and of other,shapes On the bottomsurface of the head 8 'Ilocat'ea plurality-of thestipple) units heretofore described, and preferably in such a mannerthat the lips of each'unit extend in a different direction from the lips.of other units and preferablyin a different direction from theleavesofall the other units. The stippleunits are preferably securedato thehead 8 by two screws i, as

shown, but :any other suitable retaining means may be employed in lieuof the The retaining devices .may be tightened until the lips of eachunit areseparated the same distance or the stippleunits may be adjustedif preferred so that-the lipsof each unit will be at a differentdistance apart from those of other units, ac-

cording to the elfects which are tobe produced, and it-will beunderstood that the adjustment of the lips of the stipple units may bechanged from time to time if desired after the brush is constructed byloosening or tightening the retaining devices for one or more or all ofthe stipple units. If, after the brush has been used, the lips of one ormore of the stipple units tend to separate more than is desired, theretaining devices for said unit or units may be tightened. to bring thelips into closer relation. For the best results, the lips of the stippleunits should be approximately perpendicular with the surface to betreatedwhen the brushis used. r

The brush head8 is asse if desired,

with a handle, for example the handle 9, projecting laterally fromthebrush header any other form of handle ,WlllCh may facilitatethe useof the brush.

In practice, the brush is applied to the Work solthat the stipple edges2.2 of all of the stipple units simultaneously come in contact with thepaintedsurface, and I have outer ends provided with stippling edges.

2. A stipple unit for stipple brushes, comprising a pair ofapproximately parallel leaves of flexiblematerial connected integrallyat one end, and provided with means for attaching the unit to a brushhead, the

.outer ends or" said leaves having stippling edges. V

8. A stippleunit for stipple brushes comprising a pair of approximatelyparallel leaves, of flexible material, having a body portion connectingthem at one end, said body portion having separated contact edges forengaging a brush head, and a recessed portion between said contactedges.

4. A stipple unit for stipple brushes comprising a pair of approximatelyparallel leaves, connected at one end by a body portion, said bodyportion being provided with contact edges substantially in line with thesaid leaves, for engaging a brush head, and

being recessed between said contact edges.

5; A stipple brush comprising a brush 7 head,'and. a plurality offlexible leaves extending therefrom,-and provided at'their outer endswith stippling edges. I

Copies of this patentmay be obtained for 6. A stipple brush comprising abrush head, and a plurality of flexible leaves projecting therefrom, andhaving their outer ends provided with stippling edges, said stipplingedges of the various leaves extending in difierent directions.

7. A stipple brush comprising a brush head, and a plurality of stippleunits, each comprising a pair of flexible, approximately parallel lips,connected at their inner ends by a body portion, and retaining devicesfor securing the body portions of said units to the brush head. 7

8. A stipple brush comprising a brush head,'and a plurality of stippleunits, each comprising a pair of'fiexible approximately parallel lipsconnected at their inneriends' by a body portion, and means forconnecting the bodyportions of said units to the brush head, the lips ofeach unit extending in a diiierent direction from the lips'ofsubstantially all the other units.

9. A stipple brush comprising a brush 75 prising a pair offlexibleapproximately 1 head, a plurality of stipple units, each comparallellips connected at their inner ends by a body portion, said body portionhaving separated contact edges for engaging the brushhead, and arecessed portion between said contact edges, and retaining devicesengaging said body portions between said contact edges.

10. A stipple head, a plurality of stipple units, each combrushcomprising a brush prising a pair of flexible approximately 7 parallellips, connected at their inner ends by a body portion,.said body'portionhaving separated contact edges, in line with said lips, and a recessedportion between said" edges, and retaining devices engaging said mainbody between the contact edges thereof for securing the said units tothe brush head,

the lipsof each unit being disposed angularly to the lips of adjacentunits.

In testimony whereof I a'iiix my signature, in the presence of twowitnesses.
